What can schools do to increase interest in science, technology, engineering, and math?

According to the National Science Board's report "Science and Engineering Indicators 2006," American students perform among the lowest internationally in the fields of science, technology, engineering, and mathematics (STEM). As the need for educated professionals in these areas skyrockets, some observers say schools do not adequately prepare students for careers in these fields, resulting in a significant lack of student interest. If this is indeed a pressing concern, as the National Science Board and other organizations suggest, what should be our priority in addressing it? We're interested in your opinion.
